Mr. Small and Marvin's house is a minor location in The Amazing World of Gumball. It first appeared in "The Job" in which Gumball and Darwin deliver him a pizza. It is the place where Mr. Small lives. It reappears in "The Watch." However, Marvin is the owner of the house in that episode, and even has the same backyard as Mr. Small. However, Mr. Small was shown as the owner once again in "The Wicked."
Mr. Small's house appears to be a modestly-sized home that is light green in coloration. The front porch of the house is decorated with various New Age paraphernalia such as dreamcatchers and wind chimes. The interior of the house is shown to be somewhat dark.
